Will you tell us if we do not need blockchain?

Yes, and we often do. If a shared database or a standard API solves the problem at lower cost and risk, we say so plainly. We would rather lose a build than sell you a ledger you do not need.

What makes a good blockchain use case?

Multiple parties who do not fully trust each other, a need for a shared and tamper-evident record, and value in removing an intermediary. If a single trusted party already controls the data, a conventional system is usually better.

What does a feasibility engagement produce?

A clear go or no-go recommendation backed by a use-case assessment, a network and architecture choice, a cost and ROI model, and a phased roadmap with a scoped proof of concept so you can decide with evidence, not hype.

Blockchain strategy and feasibility

An honest assessment of whether blockchain fits, and the roadmap if it does.

Before you invest, we assess whether blockchain genuinely solves your problem or whether a database serves you better. We run decision-framework workshops, model the trust and cost case, choose the right network type, and produce a phased roadmap with a proof of concept. We tell you when not to use blockchain, which saves clients far more than another rushed pilot ever would.

How we engage

A clear path from problem to outcome

Discovery and protocol selection

We map your use case, trust model and stakeholders, then choose the right chain and consensus: public EVM (Ethereum, Polygon, Base, Arbitrum), a permissioned ledger (Hyperledger Fabric, Quorum), or a Layer 2. We confirm whether a blockchain is actually warranted before any code is written.

Architecture and threat modelling

We design the on-chain and off-chain split, data and key-management model, gas and fee strategy, and upgrade path. Every contract is threat-modelled against known attack classes (reentrancy, access control, oracle manipulation) so security is built in, not bolted on.

Build, test and audit

We develop in Solidity, Vyper or chaincode with full unit, fork and invariant test coverage using Foundry or Hardhat. Contracts go through static analysis (Slither), fuzzing and an internal security review before any deployment to a public or production network.

Deploy, verify and operate

We deploy with reproducible scripts, verify source on the explorer, and hand over runbooks, monitoring and indexing (subgraphs, event listeners). Optional managed operations cover key rotation, upgrades and incident response after go-live.
